abstract = "The present work shows the temporal evolution of the Doce River
discharge and turbidity plume at the Esp{\'{\i}}rito Santo
coast, southeast Brazil, using in situ data and Landsat images
from 1985 to 2016. MODIS-Aqua imagery was used to analyze changes
in the dispersion of the plume under influence of synoptic
atmospheric systems. Turbidity maps were obtained using a globally
parameterized model, which had a reasonable comparison with in
situ data obtained at the river mouth. The Doce River watershed
has been suffering from various environmental e.g., precipitation
variability, and anthropogenic stressors e.g., land-use changes,
impacting the quality and volume of the river over the years, with
an overall negative discharge tendency, and a high interannual
variability, with frequent flooding events, causing higher
turbidity. In 2015 the river faced its worst disaster with the
collapse of a mining waste water dam, which increased turbidity,
despite the low discharge caused by a drought season. The denser
turbid plume traveled up to ~13 km towards the southern shelf, and
the diluted plume more than 75 km, as during high flooding events.
Changes on the dominant wind pattern from NE to S, can change the
dominant flow of the plume from S to E-NE, and increase turbidity
over the northern shelf, with contribution of other rivers and
bottom resuspension. The Doce River plume should be monitored with
satellite imagery and in situ campaigns as flooding events are
likely to occur and may still wash out mud accumulated in the main
river.",
